Abstract

The invention discloses a method for determining power headroom, which is used for terminal equipment and comprises the following steps: determining a reported PUSCH (Physical Uplink Shared Channel) for sending a power headroom report, with the reported PUSCH being located on a first carrier; and in a target carrier, determining at least one symbol in a first time slot overlapped with the time slot in which the reported PUSCH is located as a target symbol set, determining the PUSCH overlapped with the target symbol set as a target PUSCH, and calculating a power margin value of the target carrier. The invention further discloses terminal equipment for determining the power headroom. The problem that the PUSCH basis for calculating the power headroom value cannot be effectively determined inthe prior art is solved.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a method and device for determining a power headroom. Background technique [0002] The network device receives a power headroom report (PHR, Power Headroom Report) from the terminal device while controlling the uplink transmission power of the terminal device. The terminal device sends a PHR to the terminal device through the MAC CE, including the PH parameters of each carrier. PH indicates the available power of the terminal equipment in addition to the PUSCH transmission power of the current carrier. If the PH is a negative value, it means that the network device has scheduled a data transmission rate for the terminal device that is higher than its available transmission power can support at that time. The PH value can be used as a reference basis for network equipment to allocate uplink resource blocks. If the PH value is negative, it means that ...
